Re: [Xen-devel] [PATCH v4 07/10] arm: add a tiny kconfig configuration
Hi,
Sorry for the formatting. Add a tiny kconfig configuration. Enabled NULL and Credit schedulers.
Support only 8 cpus. It only carries non-default options (use make
olddefconfig to produce a complete .config file).
Signed-off-by: Stefano Stabellini <sstabellini@xxxxxxxxxx>

Note that this approach has a limitation: it is not possible to "select
a range". In other words, using tiny.config NR_CPUS is set to 4. It is
not possible to increase it to 8 from config RCAR3.
Is that still true? I thought we discussed a solution to do it yesterday.
By that, I mean the platform would be selected at olddefconfig.
Cheers,
